Question

我正在使用建议将新的有效载荷标头发送到成功通道，在成功通道中，我正在使用outboundAdapter将file_originalFile发送到FTP服务器，但是我遇到了一个问题，即成功通道将文件发送为.msg和.msg旁边，当我想将foo.csv自身发送到ftp服务器时，可以看到显示file_originalFile名称的文本。

有什么可能的解决方案？

这是应用程序的代码

public IntegrationFlow localToFtpFlow(Branch myBranch) {

    return IntegrationFlows.from(Files.inboundAdapter(new File(myBranch.getBranchCode()))
                    .filter(new ChainFileListFilter<File>()
                            .addFilter(new RegexPatternFileListFilter("final" + myBranch.getBranchCode() + ".csv"))
                            .addFilter(new FileSystemPersistentAcceptOnceFileListFilter(metadataStore(dataSource), "foo"))),//FileSystemPersistentAcceptOnceFileListFilter
            e -> e.poller(Pollers.fixedDelay(10_000)))
            .enrichHeaders(h ->h.header("file_originalFile", "new java.io.File('/BEY/FEFOexport" + myBranch.getBranchCode() + ".csv')",true))

            .transform(p -> {
                LOG1.info("Sending file " + p + " to FTP branch " + myBranch.getBranchCode());

                return p;
            })
            .log()
            .handle(Ftp.outboundAdapter(createNewFtpSessionFactory(myBranch), FileExistsMode.REPLACE)
                    .useTemporaryFileName(true)
                    .autoCreateDirectory(false)
                    .remoteDirectory(myBranch.getFolderPath()), e -> e.advice(expressionAdvice()))

            .get();
}

@Bean
public Advice expressionAdvice() {
    ExpressionEvaluatingRequestHandlerAdvice advice = new ExpressionEvaluatingRequestHandlerAdvice();
    advice.setSuccessChannelName("success.input");
    advice.setOnSuccessExpressionString("payload.delete() + ' was successful'");
    //advice.setFailureChannelName("failure.input");
    advice.setOnFailureExpressionString("payload + ' was bad, with reason: ' + #exception.cause.message");
    advice.setTrapException(true);
    return advice;
}

    factory.setPassword("spicysilk");
    return factory;
}

Answer 1

.enrichHeaders(h ->h.header("file_originalFile","/someDirectory/FEFOexport" + myBranch.getBranchCode() + ".csv",true))

标头仅包含文件名，而不包含File。发送字符串时，它将成为远程文件的内容。在这种情况下，默认情况下，远程文件名使用FileHeaders.FILENAME；如果没有这样的标头，则使用<messageId>.msg。

使用

.enrichHeaders(h ->h.headerExpression("file_originalFile", "new java.io.File('/someDirectory/FEFOexport" + myBranch.getBranchCode() + ".csv')",true))

成功通道发送.msg文件而不是.csv文件
